Question is, how do you know that you are really braking as hard as possible without locking the wheels up? The amount of adhesion you have depends on the surface, the car/brake combo, whether you are turning etc etc. ABS takes all those variables away.
I used to be a tutor for the Prodrive programme, so we had an opportunity to do little bits of experimentation during our training, just to verify things ourselves. In the 90 degree corner they set up I personally tried threshold braking (braking as hard as possible without lockup) and pulse braking and I found I could consistently brake later and retail control with the pulse braking. Then taking the Sentra through the same corner with the ABS it worked pretty much exactly the same as the pulse braking - same braking point, same amount of retardation.
Remember, ABS used to be legal in F1 but it was outlawed. If F1 teams thought they had a braking advantage by using ABS then surely the same applies to Joe Average on the road? Having had it on my car and used it in many situations and I personally wouldn't own a road car (by choice) without it.
[Edit] Thinking about it I guess the same applies to traction control, stability control etc. If the worlds best drivers think it helps them control the car better and makes it less likely for them to have an accident by having such systems fitted then surely the safety of us mere mortals would be improved by having similar systems fitted to our cars?
We know that four-wheel drive doesn't work in a racing car, and I proved to myself that it doesn't work very well for rallycross. I'm absolutely convinced that it has no future in rallying, either, even if the regulations allowed it. - Roger Clark (rallying legend), circa 1976
